Remapping constant points in a white-box implementation

The non-transitory machine-readable storage medium of claim Error! Reference source not found, further comprising:

• instructions for encoding the output data according to a selected one of a plurality of encoding schemes, wherein the encoding scheme is selected out of a plurality of encoding schemes based upon selection data which depends upon the input message;
• instructions for receiving in a next round of the cryptographic operation the encoder output as input;
• and
• instructions for compensating for the effect of the encoding according to a selected one of a plurality of recoding schemes based upon the selected recoding scheme out of the plurality of recoding schemes based upon the selection data.

A method of producing a cryptographic implementation of a cryptographic operation mapping an input message to an output message, wherein the cryptographic operation includes at least one round including a non-linear mapping function configured to map input data to output data, comprising:

• producing a cryptographic implementation of the cryptographic operation wherein the cryptographic implementation is configured to:
• determine that the input data has a diversification number less than a diversification level threshold number;
• remap the input data to a remapped input data, wherein the remapped input data corresponds to an input data having a diversification number greater than or equal to the diversification threshold value, and
• input the remapped input data into the non-linear mapping function to obtain output data.
